Scientists will set out in the next week to study an Antarctic realm that has been hidden for thousands of years.
A British Antarctic Survey-led team will explore the seabed ecosystem exposed when a giant iceberg broke away from the Antarctic Peninsula in 2017.
The organisation has also released the first video of the berg, which covers almost 6,000 sq km.
Its true scale begins to emerge in a shot filmed from an aircraft flown along its edge.
An international team will spend three weeks, from February to March, on board the research ship RRS James Clark Ross, navigating ice-infested waters to reach the remote Larsen C ice shelf from which the berg calved.
